I have a classic widget area that contains a custom sidebar for my homepage. It was displaying fine for a long time, but it seems that at some point an update must have broken something, and it now does not display anything.
When I go to Appearance - Widgets, I see that the widget (called Main Sidebar) is there with its contents (the contents are dynamic and so generate an exception when viewed in Widgets, but works fine when viewed live). However, when I go to the Page Builder for my home page and look at the Classic Widget Area that is supposed to contain the widget, it is now empty, and I cannot assign to it the Main Sidebar widget.
I would really appreciate some help with this issue.
